I'm aware of this ... but here is what I see:

  werner/bash> xterm -e bash -l
  [switch over to new xterm]
  address@hidden:/usr/src/werner/bash> echo $BASH_VERSION 
  address@hidden:/usr/src/werner/bash> echo ooo
  [hangup due closing xterm]
  werner/bash> bash
  address@hidden:/usr/src/werner/bash> echo ooo

... it seems to work here.

If it does not work for you, you may try to add the

  int maybe_append_history (char *filename) __attribute__((destructor(1)));

before the definition of maybe_append_history() in bash-4.2/bashhist.c
